Practical tip for those dealing with wildfire smoke now: you can make a very effective air filter for a reasonable amount of money using a box fan & one of those filters meant for your furnace.
Also, I've managed to pick up 2 of the box fans for very cheap/free from yard sales. Make sure you get a filter rated for wildfire smoke, I think this one cost about $20.
These make a huge difference in the indoor air quality.
